A PRISMA-compliant systematic review and analysis on color image encryption using DNA properties

During recent years, various encryption algorithms have been proposed for color image encryption based on DNA encoding. Image encryption is one of the most important areas of research which has taken attentions of researchers all over the world that is applicable in transmitting medical images over the insecure communication channels. In this study, a systematic review on DNA based encryption algorithms solely developed for RGB color images is performed in the period of 2000 to 2017. The comparison results on 11 included studies in terms of key space, correlation coefficient, NPCR, UACI, and information entropy showed that there were no significant improvements among the encryption algorithms using the Lena image. In conclusion, for assessing the performance of these kinds of encryption algorithms, development of large sets of benchmark image databases along with publicly available source codes or web servers are highly essential.
